Build guide:

  1. Cut female header pins flush with board before soldering to maximize clearance between board and frame.  This is useful for fitting a battery strap.
  2. Solder the Pololu regulator in place, but do not position the plastic header strip between the boards as this will not provide enough clearance for the flight controller.  The back of the regulator should be flush with the PDB.  Add a layer of electrical tape between the Pololu and the PDB.
  3. Install the PDB to your frame with the included hardware.  From the bottom, the order should be: steel screw, frame, nylon nut, PDB, nylon 6mm standoff.
  4. Remove the male header pins from the plastic strip, and insert into the female headers where needed (only one set of ground and 5V pins are needed on the large header block).
  5. Install the flight controller, positioning the pins through the holes in the flight controller.  Install a nylon nut on the metal screws to secure the flight controller in place.
  6. Solder and trim the flight controller pins to length.
  7. The tricky part is done.
  8. Remove the flight controller, tin the remaining pads, and solder your ESCs, ESC signal wires, and FPV gear to the PDB.
